Abstract (en)
[origin: EP0807719A1] A hydraulic excavator includes a revolving upper structure (1) having a rear half swingable within the width of the machine. The revolving upper structure (1) has a front portion on which a cab (3) is disposed. An internal combustion engine (17) is mounted in the rear of the cab. Various components including a direction control valve (18), a hydraulic oil tank (19), and a fuel tank (20) are mounted alongside the cab (3). The revolving upper structure (1) has a front end portion supporting thereon a bracket (12), and a boom pivotally mounted on the bracket (12) for undertaking a swing motion within an angular range of an angle less than 180 DEG . The swing angle is so set as to extend over a greater extent on one side located close to the cab than on the other side remote from the cab (3). The revolving upper structure (1) further includes a projecting portion (4b) swelling out into an area kept out of the swing range of the boom. With the projecting portion (4b) thus provided, an internal space of the revolving upper structure (1) available for mounting various components can be enlarged. <IMAGE>
